摘　　要：跨孔电磁波透视在探测地下裂隙带、溶洞等方面具有独到之处。通过分析软土、土洞的发育规律以及它们与溶洞、溶槽的关系,可间接探测软土和土洞的分布。文中探测实例说明,充分了解场地的岩溶地质特征,可帮助我们优化设计、获取有效数据、识别异常,提高该方法的应用效果。The cross-hole electromagnetic wave-penetrating method has particular advantages in detecting ground fracture zones and caves. It can also be used to detect indirectly the distribution of soft soil and soil caves by analyzing their development regularities and their relationships with caves or grooves. Examples in this paper show that this method can optimize design, obtain valid data, identify anomalies and improve application effects on the basis of fully understanding the karst geological characteristics.
